Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An individual who has two of the same allele is said to be ____
A
Homozygous
B
Hemizygous
C
Homologous
D
Heterozygous
Explanation: 

Detailed explanation-1: -If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.

Detailed explanation-2: -Listen to pronunciation. (HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.

Detailed explanation-3: -Homozygous Homozygous, as related to genetics, refers to having inherited the same versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker.

Detailed explanation-4: -An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive.
